Why do buyers want a commercial cleaning company, and where do they get burned?
Buyers want commercial cleaning because the revenue comes from written contracts with businesses, not one-off jobs, and the company owns little that wears out. A strong target has 70%+ of revenue under written commercial contracts with 12+ months remaining, 90%+ annual retention on those accounts, no customer above 12-15% of revenue, and 80%+ of staff retained for 12 months with a site lead at every major account. Contracts run 12 to 36 months with annual CPI or 3% escalators, so price increases flow through without a renegotiation.
The catch is the cancellation clause. Those same contracts carry 30 to 60 day cancellation rights. A 36-month term protects you only while the customer is happy with the crew that shows up at night. The contract file proves there is a relationship. It does not guarantee the revenue, and the relationship can sit with the seller personally.
Where buyers get burned. These risk factors move price. Here is the multiple reduction each one carries in the industry data:
- Owner manages key accounts or renewals: 1.0x to 2.0x off the multiple. If facility managers call the seller, the renewal risk is yours after closing.
- A single customer above 20% of revenue: 0.5x to 1.0x off.
- Annual employee turnover above 30%: 0.25x to 0.75x off. Constant turnover means constant rehiring and retraining, and it shows up in service complaints.
- Cash-basis or inconsistent records: a 0.5x to 1.5x discount once a quality of earnings review re-cuts the numbers.
- W-2 vs 1099 misclassification: leads to re-cut earnings and escrow holdbacks.
- Under 50% contracted recurring revenue, or month-to-month contracts without assignment clauses: the customer has no obligation to stay with a new owner.
Who you are bidding against, by size
Four buyer groups are active in this industry. Each one fits a different size of company:
- Individual owner-operators fit companies with $200K to $1M of SDE. They finance with SBA 7(a) loans and run the business themselves.
- Search funds fit companies with $1M to $5M of revenue. They buy a business that one full-time CEO can grow.
- PE-backed janitorial platforms buy add-ons with $1M to $8M of EBITDA. Kleen-Tech Services, acquired by Rainier Partners in Sep 2025, is seeking janitorial add-ons. 4M Building Solutions, backed by O2 Investment Partners, has made 16 acquisitions since Jan 2023. Kellermeyer Bergensons Services (Cerberus Capital Management) and Pritchard Industries (Littlejohn & Co.) are in the same group.
- Facility services consolidators such as ABM, Cintas, Sodexo, and Compass Group buy companies in the $5M to $100M+ EBITDA range.
Below $1M of SDE, you compete with other SBA-financed individuals and search funds. Above $1M of EBITDA, Rainier Partners, O2 Investment Partners, and similar sponsors bid through their platforms.
How much does it cost to buy a commercial cleaning company?
Small cleaning and janitorial businesses sell on a multiple of SDE. BizBuySell data on 797 sold listings from 2021 to 2025 puts the middle half of closed sales between 1.57x and 2.66x, with a 2.07x median. That category includes residential cleaning, so a pure commercial book with signed contracts should be judged on its contracts, not on the category average. Larger companies sell on EBITDA. Ad Astra gives a headline range of 3.5x to 7x EBITDA. Its 5.5x median is labeled extrapolated for a $1M to $3M EBITDA profile, and its 7.0x top quartile comes from an illustrative $1.4M EBITDA deal.
| Profile | Earnings measure | Low | Median | High | Buyers that fit |
|---|---|---|---|---|---|
| Owner-operated company, middle half of sold businesses ($81,740 to $232,721 SDE; $232,178 to $874,153 revenue) | SDE | 1.57x | 2.07x | 2.66x | Individual owner-operators, SBA-financed |
| Contracted company with management, $1M to $3M EBITDA | EBITDA | 3.5x | 5.5x (extrapolated) | 7.0x | PE-backed platforms buying add-ons, search funds at the lower end |
| Platform, $5M+ EBITDA | EBITDA | 9.0x | n/a | 12.8x | Facility services consolidators and sponsors |
The 12.8x figure is ABM's acquisition of Able Services in Aug 2021, at $65M of EBITDA, and the same source calls it a strategic ceiling. Do not use it to price a company that one owner runs. Apply SDE multiples only to SDE and EBITDA multiples only to EBITDA. A listing priced at 5x SDE because a platform paid 5x EBITDA is mixing the two.
Worked example: pricing a $450,000 SDE target
The target has $1,800,000 of revenue and $450,000 of SDE, a 25% SDE margin. That SDE sits above the $232,721 upper quartile of sold businesses. The listing applies the 2.07x median SDE multiple: $450,000 × 2.07 = $931,500. Run the same SDE through the quartile multiples and the range is $450,000 × 1.57 = $706,500 to $450,000 × 2.66 = $1,197,000. The contract file, customer concentration, and the owner's role in renewals decide where in that range the company belongs. With $1,800,000 of revenue, this company also fits a search fund's $1M to $5M revenue range, so expect competition.
Where to find a commercial cleaning business for sale
Listing marketplaces and broker listings are where a commercial cleaning business for sale shows up in public. Every buyer on those sites sees the same listing, and the asking price was set before you arrived. Filter out residential maid services, which share the category. Then screen each listing for three items: the share of revenue under written contracts, the largest customer's share, and whether the owner still cleans or sells. Off-market owners who have not listed are the other channel. They are reached through direct outreach, not search filters.
How to read a listing's SDE and add-backs before an LOI
SDE is net profit plus one owner's full compensation plus documented add-backs. EBITDA is SDE minus a market-rate salary for a manager to replace that owner. Before you sign an LOI, ask for the add-back schedule with support, revenue by customer, the last two fiscal years of tax returns, and the trailing twelve months. Add-backs a lender will accept look like this:
- Owner compensation, normalized for one owner only. If a spouse is on payroll and does real work, that salary stays as a cost.
- Personal expenses run through the business, with receipts.
- One-time costs, with invoices showing they will not recur.
- Related-party rent normalized to market. If the seller charges the company below-market rent on a building they own, normalizing lowers SDE.
Labor savings from paying cleaners on 1099 when they should be W-2 are not an add-back. They are an understated cost. Our guide to add-backs covers the documentation standard. Ask the broker for the add-back schedule with receipts and revenue by customer before you submit an LOI, because both set the multiple you can defend to a lender.
How do you finance a commercial cleaning acquisition with an SBA loan?
Use an SBA 7(a) loan. Commercial cleaning companies are SBA-eligible, and the program lends up to $5M. Under SOP 50 10 8.1, in force since October 1, 2026, a complete change of ownership needs 10% equity and at least 1.25x debt service coverage on historical results. That 1.25x is an SBA requirement for buying a business, measured on the last fiscal year or a two-year average. Projections can be reviewed, but they cannot be used to meet it. The 1.15x figure applies only to a Business Expansion, where an existing cleaning company buys another company in the same industry group.
The SBA 7(a) mechanics that apply to this deal
- Equity injection: 10% of total project cost. Project cost covers everything needed to complete the change of ownership: price, closing costs, the guarantee fee if financed, and working capital. Up to half may be a seller note on full standby, so 5% buyer cash plus a 5% standby note is a common structure. Advisory and agent fees you pay do not count toward equity.
- Standby note: no principal or interest payments for the entire term of the 7(a) loan, documented on SBA Form 155. Interest may accrue and be paid after the SBA loan is paid in full. The note stays on standby for the life of the loan.
- Term and rate: the business acquisition portion amortizes over a maximum of 10 years. On loans above $350,000, the variable rate cap is prime plus 3.0%. With prime at 7.00% since September 17, 2026, that cap is 10.00%.
- Guarantee and fee: the SBA guarantees 75% of loans above $150,000. For FY 2027, loans of $700,001 to $5,000,000 pay an upfront fee of 3.5% of the guaranteed portion up to $1,000,000.
- Valuation: above a $350,000 business purchase price, the lender orders an independent valuation from a Qualified Source (ASA, CBA, ABV, CVA, or BCA credential), prepared for the lender. The SBA loan plus any seller debt not on full standby cannot exceed that valuation.
- Quality of earnings: required when the business purchase price is $3,000,000 or more on an Initial Acquisition. The report must include a cash proof, and the lender uses its normalized earnings for the coverage test.
Worked example: the $931,500 target with $100,000 of buyer cash
| Line | Calculation | Amount |
|---|---|---|
| Purchase price | $450,000 SDE × 2.07 | $931,500 |
| Required equity (on price only) | 10% × $931,500 | $93,150 |
| Seller note on full standby | 5% × $931,500 | $46,575 |
| Buyer cash | Assumed for this example | $100,000 |
| SBA 7(a) loan | $931,500 − $100,000 − $46,575 = $784,925 | $784,925 |
| SBA guaranteed portion | 75% × $784,925 = $588,693.75, rounded to $588,694 | $588,694 |
| Upfront guarantee fee | 3.5% × $588,694 = $20,604.29, rounded to $20,604 | $20,604 |
| Maximum variable rate | 7.00% prime + 3.0% | 10.00% |
The loan is the $931,500 price minus $100,000 of buyer cash minus the $46,575 standby note: $931,500 − $100,000 − $46,575 = $784,925. The guaranteed portion is $784,925 × 75% = $588,693.75, rounded to $588,694, and the upfront fee is $588,694 × 3.5% = $20,604.29, rounded to $20,604. The standby note of $46,575 equals exactly half of the $93,150 requirement, which is the maximum allowed. Your $100,000 covers the cash half with room left over. If you finance the $20,604 fee and closing costs, project cost goes up and the lender recalculates the 10% on the larger number. Because $931,500 is above $350,000, the lender orders the independent valuation. If it comes in below the price, the gap must be filled with your cash or more standby debt. The deal is below $3,000,000, so the SBA does not require a quality of earnings report, though you can still order one.
For the coverage test, the lender takes EBITDA, which is the $450,000 SDE minus a market-rate manager salary. It divides that by a year of payments on the $784,925 loan at the note rate over 10 years. The standby note's payments are left out because it pays nothing. Cleaning equipment you add at closing can be financed over 10 years or less, and those payments also count against coverage. Enter your own SDE, price, and rate in the SBA loan calculator to see whether the deal clears 1.25x before you make an offer.
What should you verify in diligence on a commercial cleaning company?
Check three things against the listing: the contracts, the crews, and the cash. Match revenue by customer to signed contracts, payroll to tax filings, and bank deposits to reported sales. No state trade license is required for janitorial services, so diligence centers on contracts, labor compliance, and insurance.
| Item | What to request | What it catches |
|---|---|---|
| Customer contracts | Every signed agreement with term, cancellation notice, escalator, and assignment clause | Month-to-month accounts, contracts that cannot be assigned, missing CPI or 3% escalators |
| Revenue by customer | Monthly billing by account for the trailing twelve months and last two fiscal years | Any customer above 12-15% of revenue; lost accounts the listing still counts |
| Bank deposits | Statements reconciled to reported revenue | Cash-basis or inconsistent records, which carry a 0.5x to 1.5x discount |
| Worker classification | Payroll registers, 1099 filings, and how crews are scheduled and supervised | W-2 vs 1099 misclassification |
| I-9 documentation | Forms for every current employee | Gaps that become your compliance exposure after closing |
| Workers' compensation | Policy, claims history, and carrier payroll audits | Payroll reported to the carrier that does not match the payroll register |
| Insurance and bonding | Certificates of insurance and bonds that customers require | Contracts that need coverage limits the business does not carry |
| Healthcare accounts | Background-check policy and MSDS/SDS records | Accounts at risk if the client audits the vendor after the change of ownership |
| Staff and site leads | Headcount by account, tenure, and turnover | Turnover above 30%; accounts with no site lead |
| Renewal ownership | Who signed the last renewal at each top account | Owner-managed renewals, the risk factor that can take 1.0x to 2.0x off the multiple |
Ad Astra flags misclassification and cash-basis records as triggers for quality of earnings re-cuts and escrow holdbacks. Both also affect how a lender verifies cash flow. The lender tests coverage on historical results it can verify, so revenue the seller cannot document will not help the deal clear 1.25x. Read our explainer on the quality of earnings report if the seller's books are cash-basis.
Sort what you find into two buckets. Recurring operating costs change earnings. If 1099 cleaners have to become W-2 employees, the added payroll tax and workers' compensation premium come out of SDE before the multiple is applied. Capital items are different. Worn floor machines, vehicles, or deferred equipment replacement come off the purchase price as a one-time dollar figure, not off SDE. Tell the seller's broker in writing which bucket each finding belongs in before you revise the LOI, so the price change has a calculation behind it.
Which deal terms matter when you buy a janitorial business?
When you buy a janitorial business, five terms decide whether the revenue you paid for is still there after closing. They are contract assignment, the seller transition, the non-compete and non-solicit, licensing and insurance transfer, and the lease.
Contract assignment
In an asset purchase, the company's customer contracts have to be assigned to your new entity. Contracts that require consent, and month-to-month accounts with no assignment clause, give each customer a free exit at closing. In a stock purchase, the contracts stay with the entity, but so does any past misclassification or payroll exposure. That is why escrow holdbacks and indemnities matter more in a stock deal.
Licensing transfer
There is no state trade license to transfer for janitorial services. Your entity needs its own local business license, general liability and workers' compensation policies bound effective at closing, and any bonds your customers' contracts require. Customers that need a certificate of insurance naming them will ask for a new one in your entity's name. Healthcare clients will also want your background-check policy and SDS records before your crews go back on site.
Seller transition
The seller transition is negotiated in the purchase agreement, and it should match the renewal calendar of the largest accounts. If the seller handles renewals, write in a duty to introduce you and your site leads to every facility manager. Also require the seller to stay involved through the next renewal at each top account. Build this into the agreement before closing. After the wire, you have no way to make the seller stay.
Non-compete and non-solicit
Customers follow the crews and the person they call. The non-solicit of employees protects the site leads that hold accounts, and the non-compete keeps the seller from opening a competing company across town. Both belong in the purchase agreement, and the customer non-solicit should name the accounts in the contract file.
Lease
A cleaning company needs little real estate, often an office and a supply room. If the seller owns the building, the rent was normalized in SDE, so sign a new lease at that same market rate. Otherwise the earnings you paid for will not match the rent you pay. Make written consent to assignment from every customer above 12-15% of revenue a closing condition in the purchase agreement.
Where does Munera fit when you buy a commercial cleaning company?
Munera's Acquisition Launch finds off-market cleaning companies for buyers and introduces the SBA lenders who finance them. This page is written by Mike Ehde, Partner. The firm works on transactions from $1M to $30M in enterprise value. It cites $200M+ in closed transactions, 4,000+ buyers in its network, 1,000+ owner conversations a month, and coverage in all 50 states.
Here is how a buyer engagement works:
- Define the box. Set the SDE or EBITDA range, geography, and contract profile you will buy. Run your cash and target price through the acquisition calculator first so the box matches your 10% injection and the 1.25x test.
- Get vetted. Owners on the sell side share their business only with buyers who have signed an NDA and been checked for capital and fit. They use a blind profile until a buyer qualifies, so have your personal financial statement and proof of funds ready.
- Get matched. A matched introduction can produce an offer within weeks, because the owner has not listed and you are not bidding against a public pool.
- Finance and close. We introduce lenders who make SBA 7(a) acquisition loans. From LOI to close takes 60 to 90 days, depending on financing and diligence.
When a business matches one of Munera's active buyer clients, the buyer pays Munera's fee and the seller pays nothing. Under SOP 50 10 8.1, advisory fees the applicant pays do not count toward the equity injection. Budget the fee separately from the 10% injection and the 5% cash portion the lender will verify against 30 days of bank statements.
Frequently asked questions
How much does it cost to buy a commercial cleaning company?+
The median cleaning and janitorial business sold for $260,000 across 2021 to 2025, and for $325,000 in 2025 alone. That median business produced $136,326 of SDE on $433,327 of revenue, so a company with a larger contracted book and a management layer will price above it. Plan for more than the price: the SBA guarantee fee, closing costs, and working capital all count in total project cost.
Can I buy a commercial cleaning company with an SBA loan?+
Yes. Janitorial companies are eligible for SBA 7(a) financing, and the SBA guarantees 75% of loans above $150,000. That guarantee is why lenders will finance a service company with few hard assets. Anyone who owns 20% or more must personally guarantee the loan, and if business assets do not fully secure it, the lender takes a lien on equity in that owner's personal real estate.
How much cash do I need for the equity injection?+
The requirement is 10% of total project cost, not 10% of the purchase price, so financed fees and working capital raise it. Up to half can be a seller note on full standby, which leaves 5% that must come from unborrowed cash or another unlimited source. The lender verifies it with bank statements showing the funds held for at least 30 days, and a gift letter or promissory note alone will not satisfy it.
What should I check in diligence on a commercial cleaning company?+
Start with the customer contract file and monthly billing by account, then reconcile payroll registers to the tax returns and the workers' compensation carrier's payroll audits. A mismatch between what was reported to the carrier and what was paid to crews can mean misclassification exposure that follows a stock purchase. Ask who signed the last renewal at each top account, because that tells you whether the relationships are with the company or the seller.
How long does the seller stay after closing?+
On an SBA 7(a) deal, a departing seller can stay on as a consultant or employee for up to 24 months in total under SOP 50 10 8.1. Within that limit, the length is negotiated in the purchase agreement, and it should cover the next renewal at each of the largest accounts. If the seller personally manages renewals, write specific duties into the agreement, such as account introductions and joint site visits, instead of a general consulting promise. Settle these terms before closing, while the price is still open.
Do I need a license to buy a janitorial business?+
No state trade license is required for janitorial services, so there is no contractor license to qualify for or transfer. You do need a local business license in your own entity, insurance and workers' compensation policies bound at closing, and any bonds your customers' contracts call for. Healthcare clients may also require your background-check policy before your crews return to their facilities.
